Answer:

Step-by-step explanation:

The line with positive slope is 3x-5y≥15 and the line with negative slope is 2x+3y≤12.

This is because such inequalities represent half planes which are divided by the corresponding lines.

Put (0,0) in both lines to check if the origin lies in the shaded half plane or not.

What is the product? (3x-6) (2x^2 -7x+1)

STALIN [3.7K]

<u>Answer-</u>

$\left(3x-6\right)\left(2x^2-7x+1\right)=6x^3-33x^2+45x-6$

<u>Solution-</u>

Given the two polynomials are $3x-6, 2x^2 -7x+1$

So their product will be,

$=\left(3x-6\right)\left(2x^2-7x+1\right)$

Distributing the Parentheses,

$=3x\cdot \:2x^2+3x\left(-7x\right)+3x\cdot \:1+\left(-6\right)\cdot \:2x^2+\left(-6\right)\left(-7x\right)+\left(-6\right)\cdot \:1$

Applying minus-plus rules,

$=3\cdot \:2x^2x-3\cdot \:7xx+3\cdot \:1\cdot \:x-6\cdot \:2x^2+6\cdot \:7x-6\cdot \:1$

Simplifying further,

$=6x^3-33x^2+45x-6$

How do you solve this step by step?

Answer:

x = -1

Step-by-step explanation:

since the 23 is positive you have to subtract it on both sides . which would give you -4x =4

then divide -4 on each side and you should get x = -1

a positive divided by a negative is always negative.
